We only use Syslog-ng where I work. We have a lot of servers that "log offsite" to a syslog analyzer so the logs can be sorted, stored, and alerts can be generated, etc. After using syslog-ng at work, I decided I couldn't live without it and set it up at home. It's really the best syslog tool I've worked with.
It should be noted that building syslog-ng requires libol which is available from the same people who write syslog-ng here. I've built libol and syslog-ng on x86 and x86-64 (both AMD and EM64T) with no problems what-so ever. It is intresting that libol is available under the GPL and not the LGPL....
"There's a big difference between "copy" and "use". It's exatcly the same
issue whether it's music or code. You can't re-distribute other peoples
music (becuase it's _their_ copyright), but they shouldn't put limits on
how you personally _use_ it (because it's _your_ life)."
